Serpentine belt broke replaced and now won't start. Has no spark but has fuel on 1995 Pontiac Bonneville

The serpentine belt broke when I was driving down the road. I replaced it and now the car won't start. I do not have spark but I do have fuel

Make sure the broken belt didn't damage the wiring to the crankshaft position sensor or the camshaft position sensor or damage the sensors themselves. The crankshaft sensor is located above the crankshaft pulley in the engine block, The camshaft sensor is between the cylinder heads behind the power steering fluid reservoir.
